| Abstract: | The main bridge of Fumin Bridge in Tianjin is a single tower and spatial cable plane self-anchored suspension bridge and the main cables of the bridge over the main span are of the three-dimensional geometric shape.In the process of system transformation,the main cables will not only cause displacement in the vertical direction,but also the displacement in the transverse direction and the positions of the catwalk have to be accordingly adjusted.In this paper,the construction methods for erection and adjustm... |
